I know this is a week early, but some are ahead of themselves, and I would hate it if they had nowhere to post their pics.
We are still on relatively easy weeks, and I didn't have any problems with this Tri. It seemed to fall into place quite nicely.
Please don't panic, I moved my RS4 to somewhere else in the quilt, so you are looking at the 'wrong' Tri here in this pic. Sorry about that.
F2, I treated each wedge separately, joined them into two groups of four, then joined the two halves.
I found K13 easy, a nine patch in the middle, and squares and half squares round it.
E3, More half squares - so fairly straighforward.
